clean the interior of an automobile, thereby eliminating hand brushing as is customary.

'Another object of the invention is the provision of a cleaner of this character, wherein the construction thereof is novel, its suction nozzle or head can be conveniently moved about within an automobile so that the interior can be thoroughly cleaned, removing all dust and dirt both upon the upholstery and floor of the automobile with the result that during the cleaning operation there will be eliminated clouds of dust that usually accompany. the cleaning by brush and also assures removal of hair and lint from the cushions within the automobile that would be almost impossible to remove by brush.

' A further object of the invention is the provi-' sion of a cleaner of this character, which is comparatively simple in its construction, thoroughly reliable and eificient in its operation, automatic of action, conveniently moved from place to place, being self-contained, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combinationand arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 6 is a fragmentary vertical sectional view through the upper portion of the cleaner.

Figure '7 is an enlarged fragmentary vertical sectional view showing the motor and the details of the coin control mechanism of the cleaner.

Figure 8 is a fragmentary horizontal sectional view thereof.

Similar reference characters indicate corre- 5 sponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the vacuum cleaner comprises a wheeled truck Ill having the pair of front wheels II and a single 10 caster wheel I2, respectively, the latter being rotatable and arranged at the rear of the truck so that the said truck can be steered and readily turned in the use of the cleaner.

Rising from this truck H1 at its front end is a vertically disposed casing l3 preferably made from cast metal although it may be otherwise formed and is adapted to be fixedly held upon the said truck. The casing l3 interiorly thereof is partitioned to provide upper and lower compartments l4 and [5, respectively, the latter constituting a space for a suction hose I6 of any desired length and when not in use is confined within this compartment I5. In the compartment I4 is arranged an electric power motor I1 5 associated with a suction device l8 to create a suction in the hose l6 and a terminal mouth piece or nozzle 19 which normally is held within a roller guide-bracket 20 upon a door 2| hinged at 22 to the casing [3, the door being opened and closed by vertical swinging movement and when opened will permit the'nozzle or mouth piece I9 to be pulled outwardly from the roller guidebracket 20, the latter being also adapted to guide the hose It on extension thereof. ing of the door 2| the hose l6 and nozzle or mouth piece l9 will be concealed within the compartment IS in the casing l3.

Arranged on the truck I0 is a platform 23 it being supported upon springs 24 and carries a saddle 25 for a depressible lever 26 pivoted at 21 to a hanger depending from the truck, the lever being provided with a foot pedal end 28 so that it may be operated by the foot for depressing the platform 23 against the tension of the springs 24 supporting said platform.

7 Releasably carried by the platform 23 is a dirt and dust collector body 29 in the form of a can open at its top where it is engageable with acapping crown or head 30 stationarily held by 5 0 a framing 3| joined with the truck Ill and the casing l3. This framing carries a handle bar 32 to permit convenient hand pushing of the cleaner.

The crown or head 30 carries a screen or filter- On the clos- 35;

2 ing disk 33 which is adapted to match the top open end of the can 29 when fitting the rim 34 of said crown or head and sealed thereby. The suction hose l-S has connection with an elbow lead 35 passing through the screen or filtering disk 33 for connection with the can 29 while the suction device 58 has connection at the suction side thereof by a pipe 38 with the crown or head 38 above the screen or filtering disk 33 so that when the suction device it is operating dust or dirt laden air will be sucked through the nozzle is, hose it directly into the can 29 whence the air free of dirt or dust as cleaned or filtered by the disk 33 will be conveyed through the pipe 36 and discharged from the suction device 18.- The elbow 35 carries a glass dome 3 which is exposed exteriorly of the cleaner to permit inspection of the flow through said elbow;

It will be apparent that when the platform 23 carrying the can 29 is lowered it may be readily separated from the crown or head 30 and removed from the platform for emptying the contents or deposit within the can.

Arran ed within the compartment I4 at one side of the motor i! therein is a coin chute 38, the latter opening through the top of the casing 53 which is provided with suitable coin entrance slot 39 registering with the chute for the admission of a coin therein. The coin chute 38 has arranged therein a coin trap including a pair of pivotally mounted retention jaws 49 and 4|, respectively, these being located opposite each other and constitute arresters for a coin in the chute 3a which latter when in the lower end portionAt ofsaid chute effects a closing of an electric circuit (not shown) having arranged therein the motor E7, the circuit receiving its current supply from any suitable source.

Arranged within the compartment I4 is a train of slow speed gearing 4?.2 operatively connected with the power shaft as of the motor I! and this gearing actuates a trip 54 movable in the path of a lift arm 35 fixed to the jaw 40 so that at a determined period the latter will be moved to permit the freeing of a coin within the chute 38 arrested thereby for. the deposit of said coin within the compartment M. This jaw 40 has linkage 57 with the jaw 44 which latter has arresting function. elevated or in advance of the arresting function of the jaw 48. When this jaw 48 trips for the release of the coin arrested thereby the jaw it by linkage M is pulled upon to protrude into an arresting position within the chute S3 forarrestin a second coin deposited within the chute 38 and thus assuring a continued operation of the cleaner. When the chute 38 is devoid of a coin therein the motor I! is passive and the circuit isopen so that the machine is inoperative.

The lower end 46 of the chute 38 is insulated from the upper portion of said chute and suitable insulation is had between the linkage 4'1 and the jaws it and ii.

It will be understood that the cleaner is movable so that it may be moved fro-m one locality to another for convenience in the use thereof and in such use it is necessary to make a deposit of a coin and the extending of the nozzle or mouth piece 19 to the point where vacuum cleaning is required. Normally the mouth piece or nozzle I9 is concealed within the compartment IS. The dust and dirt laden air will be filtered in the operation of the cleaner and the deposit of the dust and dirt will be assured within the dust collector or can 29.

The trip 44 in its travel meters the time of action of the cleaner for vacuum cleaning purposes.

1. A machine of the character described comprising a truck, a depressible platform on said truck, a dirt and dust collector body on the platform, a casing rising from the truck at one side of the platform and having separated compartments, at capping crown stationarily held and closing the collector body when upon the platform, an electrically operated suction mechanism within one of the compartments and communicating with the collector body through said crown, a suction hose connected with said suction mechanism and within the other compartment for access to permit the drawing of said hose outside of said casing, a nozzle at the free end of said hose,-and foot operated means for depressing the platform to disengage the collector body from the capping crown.
